Definitions
- the invention is based on a circular connector with a shield connection, in particular for circular connectors with a push-pull lock according to the generic type of independent claim 1.
- Circular connectors of this type are required in order to connect cables, in particular containing electrically conductive wires, to devices and/or other cables.
- cables and connectors are required that have a high level of electromagnetic compatibility (EMC).
- EMC electromagnetic compatibility
- cables and some of the wires they contain are sheathed with conductive wire, wire mesh and/or foil.
- various means of shield connection are used.
- resilient elements made of electrically conductive materials are preferably used in order to transfer an electromagnetic shield from an electrically conductive cable to a mating connector via a connector.
- spring washers are usually recommended, particularly with circular connectors.
- corrugated spring washers for the shield connection is particularly popular with circular connectors.
- German Patent and Trademark Office has researched the following prior art in the priority application for the present application: DE 102017 124 141 A1 and US 4,544,224 A.
- the object of the invention is to equip known circular plug connectors with push-pull locking around an element for shield connection, which element can be produced easily and cost-effectively and can be used reliably.
- One embodiment of the invention provides a circular connector for the detachable connection of lines, having at least one housing element for accommodating at least one insulating body and at least one locking element for detachable connection to a mating connector, the housing element accommodating at least one peripheral spring element and the spring element for connecting an electromagnetic shield is made of an electrically conductive material and wherein the spring element is held in a circumferential depression of the housing element and has at least two radially outwardly pointing bulges.
- lines preferably means electrically conductive cores of a cable.
- an optical signal line or a combination of electrically conductive wire and / or optical Signal line and / or a fluid line are used.
- the “housing element” means in particular at least one electrically conductive component of the circular connector, which is located in the connection area with a mating connector.
- the housing element is particularly preferably designed as a metallic sleeve.
- a circular connector can have various housing elements, for example a union nut for connecting the circular connector to a strain relief and/or a cable outlet.
- Plastic cylinders which have at least one through-opening for receiving at least one contact element, are usually used as the insulating body.
- the contact element connects the electrical and/or optical and/or fluid transmission to a corresponding contact element.
- the corresponding contact element is usually located in a mating connector that corresponds to the circular connector or in a corresponding attachment housing.
- the locking element means a component which interacts with the mating connector in such a way that an undesired release of the plug connection is prevented.
- the spring element according to the invention for shield connection is particularly advantageous when using a so-called push-pull locking mechanism.
- Such locking mechanisms are designed with latching shapes, so that when the connectors are plugged together, the respective latching shapes interact with one another. This connection can be easily released by applying a tensile force to the housing element provided for this purpose by means of release forms, for example catch hooks, in at least one of the plug connectors.
- the release shapes act, for example, on at least one locking element and release it from the corresponding locking element.
- the spring element according to the invention is made from an electrically conductive material.
- the spring element is made of metallic materials, in particular alloys containing copper are provided, and the use of copper-beryllium alloys is very particularly preferred.
- alternative alloys, for example spring bronze, and/or other materials are conceivable, for example spring steel.
- at least one radial groove in which at least one ring of the spring element can be inserted is to be understood as an indentation. Bulging means that the outer diameter of the spring element is deformed outwards by at least half the thickness of the spring element. The bulge ideally takes on a new diameter that is greater than or equal to the inside diameter of a mating connector.
- the spring element has at least one recess, the recess enabling the diameter to be reduced and thus initially at least simplifying a plug-in process.
- the recess allows the spring element to yield at least during the insertion process of the circular connector with a corresponding mating connector, so that the mating connector can be brought into engagement with the circular connector. The bulges then ensure contact with the mating connector, while the spring element in the recess ensures reliable contact with the circular connector.
- the recess enables quick and uncomplicated assembly of the circular connector.
- the spring element can be widened in a flexible deformation area in order to be guided over a housing element and inserted in a peripheral depression.
- the bulges of the spring element each have at least one bulge pointing radially inwards indentation up.
- This bulge ensures that at least two areas of the bulges point outwards and protrude beyond an outer diameter of the spring element, while the bulge is deformed inwards by at least half the thickness of the spring element.
- the indentation is formed in such a way that the diameter of the spring element again assumes the outer diameter at the deepest point of the indentation.
- the bulges make contact with a mating connector, while the bulges ensure contact with the circular connector.
- the indentation is arranged essentially in the center of each bulge. In particular, this ensures the shield connection of the circular connector to the mating connector.
- a further embodiment provides for the bulges on the spring element to be arranged at a distance of 100° to 140° from one another.
- the at least two bulges are arranged, for example, at the positions 0° and 100° on the circumference of the spring element.
- three bulges are placed at positions 0°, 120° and 240°. In this way, shield transmission can be ensured both on the circular connector and on the corresponding mating connector.
- the bulges and indentations extend alternately along at least half the length of the spring element. In a preferred embodiment, the bulges and indentations alternate from a first end of the Spring element up to a second end of the spring element. The first and second ends are formed by the recess.
- a further embodiment provides that the bulges and at least the indentation ensure that when the circular connector is plugged into a mating connector, the spring element is clamped in a non-positive manner between the circular connector and the mating connector. This means that the spring element with bulges and indentations presses against the circular connector and a corresponding mating connector in order to enable secure shield transfer. Due to the spring force of the spring element, this screen transfer can also be maintained during movements during the operation of a working machine.
- a particularly advantageous embodiment provides that the depression is arranged behind the locking element, viewed in the insertion direction. This means that when a corresponding mating connector is plugged into a circular connector according to the invention, the mating connector first contacts the spring element before the locking elements of the mating connector are brought into engagement with the locking elements of the circular connector.

- FIG. 1 shows the plug-in area of one according to the invention
- Circular connector 1 wherein the circular connector 1 has at least two housing elements 2 and 2'.
- the housing element 2 accommodates an insulating body 3 .
- Recesses in the housing element 2 accommodate the locking elements 4 along the circumference of the housing element 2 .
- the locking elements 4 are designed as latching hooks and are provided for a push-pull locking mechanism.
- the spring element 5 for the shield connection can also be seen on the housing element 2 .
- the spring element 5 is located in a recess 6, which is designed as a circumferential groove.
- the spring element 5 is secured in the axial direction by this depression 6 .
- the spring element 5 is shown in FIG. 2, the design being clarified.
- the spring element 5 has three bulges 7, each of which has an indentation 8 in its center.
- the bulges 7 extend beyond the outside diameter dAdes the spring element 5 .
- the indentations 8 are formed in the center of the bulges 7 and at their lowest point reduce the diameter to at least the outer diameter dA or beyond.
- the spring element 5 has a recess 9 for mounting and mounting purposes.
- the recess 9 can ensure a brief evasive movement during the plugging process, which simplifies the plugging process between the circular connector 1 and the mating connector.
- the bulges 7 are essentially arranged at positions which would be indicated by an imaginary equilateral triangle within the spring element 5 .
- the indentations 8 can be used as corner points of the imaginary triangle.
- FIG. 3 shows a circular connector 1 in a front view, opposite to the insertion direction Rs.
- the functioning of the improved spring element 5 for screen transmission becomes clear.
- the spring element 5 introduced into a recess 6 is basically in contact with the housing element 2, with the bulges 7 protruding beyond the depth of the recess 6 designed as a circumferential groove.
- a mating connector fixed with the locking element 4 on the circular connector 1 presses the bulges 7 in the direction of the center point of the circular connector 1.
- the bulges 7 contact the mating connector and the resulting force acting on the bulges 7 causes the rest of the spring element 5, in particular the indentations 8 are pressed against the housing element 2, as a result of which there is reliable and permanent contact and an equally reliable shield transfer is achieved.
- FIGS. 4, 5 and 6 A comparable or identical circular connector 1 is shown in FIGS. 4, 5 and 6, which accommodates an alternative embodiment of the spring element 5' according to the invention in the depression 6 designed as a circumferential groove.
- the spring element 5' fulfills essentially the same function as the spring element 5.
- the bulges 7 and the indentations 8 alternate along the entire circumference.
- Both embodiments of the spring element 5 and 5 ' are due to the bulges 7, which exceed the average outer diameter dA, a secure contact with a mating connector.
- the forces occurring against the bulges 7 in the plugged state of the circular connector 1 with a mating connector force the indentations 8 to a Diameter less than or equal to the average inner diameter di, which ensures that the circular connector 1 is contacted. Due to this clamping effect, the electrical shield connection is always guaranteed, even during operation of a work machine with high levels of vibration.
